为什么没有建立更新日志？

我建立了一个脚本文件如下：然后调用它，这么写对么？当我运行时（错误日志有），报错为:
^G/usr/local/mysql040225/bin/mysqld: File './log/update.log' not found (Errcode: 2)
040302 13:56:03  Could not use ./log/update.log for logging (error 2). Turning logging off for the whole duration of the MySQL server process. To turn it on again: fix the cause, shutdown the MySQL server and restart it.
040302 13:56:03  InnoDB: Started
/usr/local/mysql040225/bin/mysqld: ready for connections.
Version: '4.0.18-standard-log'  socket: './mysql.sock'  port: 3308
040302 14:06:50  mysqld started
于是我自己建立了update.log 文件，运行时数据库更新，却也没有在该文件里写进更新信息，不知这是怎么回事
这是我的脚本
#!/bin/sh
rundir=`dirname "$0"`
echo "$rundir"
/usr/local/mysql040225/bin/safe_mysqld --user=mysql --pid-file="$rundir"/mysql.pid --datadir="$rundir"/data "$@"\
-O max_connections=500 -O wait_timeout=600 -O key_buffer=32M --port=3308 --socket="$rundir"/mysql.sock --log-update="$rundir"/log/update.log --err-log="$rundir"/log/err.log&
